Ancient Mariner

It was definitely taken after 1989, since the top Marshall head is a Jubilee. A black one, which came out in 1988. Maiden didn't use Marshalls during 86-89 period, so it has to be NPFTD sessions at the Barnyard.

True, but I don't know when Steve acquired the house (I suspect it was after World Slavery tour)

Also, could it be that Dave used that Mesa Boogie on some of the solos on NPFTD/FOTD? I always tought that his sound got somehow more smooth during that period... I contributed that to the CAR Jackson with Duncans, but now that I see that Boogie...

Well, TBH, I was never a fan of Adrian's Lados (let alone that hideous bass of Steve's), especially the gray burst one. The black one as a whole looked much better. And those strange ugly Rockinger tremolos... In addition the Les Paul sounds so much better on Live After Death (but that guitar is so magical that no other guitar of H's comes close to it sound-wise IMO, except maybe the new Black LP Standard he bought in 2017).

I've found some sources stating the use of Mesa Boogie amps along with Marshall amps going back as far as Powerslave era. But it is known that Janick is a long time user of Mesa Boogie amps, so they could definitely have been used on NPFTD and FOTD.

I think they are probably used mostly by Janick in studio, as Janick is known to having included Mesa Boogie studio preamps in his gear. Recording and mixing three guitarists is not an easy task. Music producers generally recommend recording guitar parts with different guitars and amps to avoid frequency conflicts during the mix stage. So I think Janick probably uses/used Mesa Boogies to avoid this as Adrian and Dave use to play through Marshalls.
